Pseudolathra
Casey, 1905
Pseudolathra is a of (: ) established by Casey in 1905. The genus comprises approximately 13 in the East Palaearctic and Oriental regions, with six species described in 2012 from Thailand, India, Pakistan, and Nepal. Species are currently divided between two subgenera: Allolathra for East Palaearctic/Oriental species and Pseudolathra for West Palaearctic species, reflecting separate phylogenetic lineages. The genus has undergone recent taxonomic revision including species revalidations, synonymies, and transfers from related genera.

Identification
Members of Pseudolathra can be distinguished from related Lathrobiini by genitalic and external morphological characters detailed in -level descriptions. The 2012 revision provides a determination for the 13 East Palaearctic and Oriental species, which are assigned to three informal species groups based on shared characteristics. Specific diagnostic features vary by species and include pronotal shape, aedeagal structure, and abdominal tergite patterns.
Distribution
East Palaearctic region (including Middle Asia) and Oriental region. Documented from Thailand, southeastern India, Pakistan, northern India, and Nepal. West Palaearctic occur in the western portion of the range.

Taxonomic History
The was revised in 2012 by Assing, who revalidated Pseudolathra pulchella (Kraatz, 1859), synonymized P. caffra javana (Cameron, 1940) with P. pulchella, and synonymized P. chujoi (Last, 1966) with P. unicolor (Kraatz, 1859). Two new combinations were established: P. nigerrima (Cameron, 1924) and P. regularis (Sharp, 1889), transferred from Lobrathium.
Subgeneric Classification
East Palaearctic and Oriental are tentatively placed in subgenus Allolathra Coiffait, 1972, while West Palaearctic species remain in the nominate subgenus Pseudolathra. This division reflects phylogenetic separation between regional lineages.
